From: Darrick J. Wong <djwong@xxxxxxxxxx> [ Upstream commit dd5532a4994bfda0386eb2286ec00758cee08444 ] Strangely, dquot_quota_sync ignores the return code from the ->sync_fs call, which means that quotacalls like Q_SYNC never see the error. This doesn't seem right, so fix that. Signed-off-by: Darrick J.
